In order to improve the breaking capacity of Hybrid DC circuit breaker and reduce the harm of DC short circuit fault to the system. we proposed a self-commutated HVDC circuit breaker based on forced zero crossing technology. The circuit breaker replaces the IGBT components with thyristors and diodes. and realizes the cut-off of the faults on both sides of the circuit breaker through a... https://www.mamapaisa.com/product-category/neutralising-shampoo/
